Analysis of dacryoliths removed at operation showed that most consisted of calcium. One consisted of ammonium and could be directly related to the presence of bacteria. Tear samples obtained from 14 patients with dacryoliths were compared with seven normal patients with regard to calcium, phosphorus, and uric acid concentrations, tear to serum calcium(More)
BACKGROUND Epithelioid sarcoma is a rare and aggressive malignancy commonly occurring in the tendon sheaths of the distal extremities of young adults. This article presents the clinical and pathologic details of two patients with epithelioid sarcoma in the orbit, the first to be reported as occurring in this location. METHODS The clinical history, results(More)
Canaliculitis must be considered in patients with chronic unilateral conjunctivitis. Pouting of the punctum, canalicular swelling and expression of particulate matter or stones are important clinical signs, and dacryocystography often helps in diagnosis. Meticulous microbiologic studies may not reveal actinomycetes. Canaliculotomy with silver nitrate(More)
Epiphora secondary to canalicular obstruction has been a perplexing problem most often treated with Jones' tube bypass surgery, which necessitates a permanent prosthesis and long-term follow-up. There are certain cases in which these problems may be avoided by using an alternative surgical approach. The canaliculodacryocystorhinostomy, a microsurgery(More)
High-frequency ultrasound biomicroscopy is a new method of examining subsurface anterior segment structures of the eye at microscopic resolution. The sclera has a high internal reflectivity and can be differentiated from the cornea, and overlying and underlying tissue. Using this modality, we examined 18 patients with various manifestations of scleral(More)
Quantitative lacrimal scintillography is a useful clinical procedure in assessing lacrimal drainage function in patients with epiphora. Examples are presented of patients with canalicular disease, lid abnormalities, 'functional blocks', and dysthroid disease, in which this technique was valuable. Information regarding the dynamics of a functioning and(More)
PURPOSE To determine whether technology is available to secure a larger-diameter Crawford tube swedged onto the metal Crawford introducer and to use the system in a closed intubation to treat a failed dacryocystorhinostomy. METHODS A metal ferrule has been developed to swedge a larger-diameter Crawford tube onto the standard Crawford probe. Seven patients(More)
A new surgical technique for reconstructing severely contracted sockets using an autogenous buccal mucous membrane-fat graft is presented. The buccal mucosa provides replacement of deficient conjunctival surface area; the fat in the underlying substantia propria of the buccal mucosa replenishes moderate volume deficiency in a single procedure. A(More)
Nonchromaffin paraganglioma (NCP), also called glomus body tumor or chemodectoma, is rarely found in the orbit. The behavior of orbital nonchromaffin paraganglioma may potentially be more aggressive than in other head and neck locations. Diagnosis depends on electron microscopic demonstration of membrane-bound neurosecretory granules. Results of(More)
